Microsoft, shrugging off licensing moves to prevent it from repeating its controversial patent deal with Novell, has signed a set of broad collaboration agreements with Linux provider Xandros that include an intellectual property assurance under which Microsoft will provide patent covenants for Xandros customers. In the meantime, Microsoft's covenant not to sue users of Novell's SUSE Linux Enterprise will be extended to all General Public License v3 users as soon as Novell includes GPLv3 code within its Linux distribution, according to the Free Software Foundation.
